First off, get your head out of your ass (excuse my language and forward attitude). "...seen by some nurse?..." -- This "some nurse" is a nurse practitioner whom probably knows JUST AS MUCH as a primary care doc. If you don't think so, then you have some research to do. Most NP's I run into are far more advanced (knowledge wise) than a doctor. Most NP's have years of experience as an RN, and because of that, their observation skills are usually much more keen; therefore, as a NP in any sort of environment, they usually do much better than a doctor. You mention that you have seen doctors get sued "when things screw up." Do you have any credible research that proves that NP's cause a higher % of lawsuites for their attending MD/DO? I HIGHLY DOUBT IT. Excuse my explosive attitude, but it angers me when doctors stick on their high horse and pretend to be know it all's. Perhaps you should stop and pay attention to what the nurses do for you. If it weren't for the nurses, you would be nothing.
To the original poster - I think being the attending over NP's would be an awesome experience (very educational as well). You will probably soon find out how awesome it is to work with NP's. Their attitudes and personalities tend to be bubbly and excited to work. Their isn't a huge malpractice risk, as the other poster suggested.
